E Pass the coolant reservoir tank
drain hose and fuel tank drain
hose through the clamp from the
outer side of the water pump inlet
pipe after routing it behind the
water pump breather hose.
The lengths of two hose ends are
allowed to be random. Any direc-
tion of cut edges can be ac-
cepted. (Only for the fuel tank
drain hose)
F Clamp the fuel tank drain hose
and fuel tank breather hose.A Clamp the leads so that they are
positioned inner of the vehicle
than the washer position after
routing them between the frame
and radiator stay. Align the clamp
position with the taping sections
of leads. Point the tip of the clamp
(surplus section) to the down
front side of the vehicle.
What the clamp fastens at this
stage are the handlebar switch
and main switch leads.
B Pass the main switch lead and
left handlebar switch lead be-
tween the frame and the heat
protector.

BLEEDING THE HYDRAULIC BRAKE SYSTEM
CHK
ADJ
WARNING
NOTE:
NOTE:
EAS00135
BLEEDING THE HYDRAULIC BRAKE
SYSTEM
Bleed the hydraulic brake system whenev-
er:

the system is disassembled.

a brake hose is loosened, disconnected or
replaced.

the brake fluid level is very low.

brake operation is faulty.

Be careful not to spill any brake fluid or allow
the brake fluid reservoir to overflow.

When bleeding the hydraulic brake system,
make sure there is always enough brake fluid
before applying the brake. Ignoring this pre-
caution could allow air to enter the hydraulic
brake system, considerably lengthening the
bleeding procedure.

If bleeding is difficult, it may be necessary to let
the brake fluid settle for a few hours. Repeat
the bleeding procedure when the tiny bubbles
in the hose have disappeared.
1. Bleed:

hydraulic brake system
a. Fill the brake fluid reservoir to the proper lev-
el with the recommended brake fluid.
b. Install the brake fluid reservoir diaphragm.
c. Connect a clear plastic hose
1 tightly to the
bleed screw
2.
AFront brake master cylinder
BFront brake caliper
CRear brake caliper
Bleeding order of the front hydraulic brake sys-
tem is the following order:
1. front brake master cylinder.
2. front brake calipers.
3. front brake master cylinder.
d. Place the other end of the hose into a con-
tainer.
e. Slowly apply the brake several times.
f. Fully pull the brake lever or fully press down
the brake pedal and hold it in position.
g. Loosen the bleed screw.
